Keeping your chain clean is essential, especially if you ride in the rain or other adverse weather conditions. Regular chain maintenance prevents rust and chain stiffness.

There are two camps in the debate over chain lubrication: proponents of lubrication and its opponents. The opponents’ argument is based on the idea that chain lubricants attract grime. When this grime becomes stuck to the chain, the opponents of lubrication believe it causes increased chain wear.

The camp promoting chain lubrication believes lubricants allow for longer chain life and reduced friction. There is little evidence to settle this debate. For more information about lubricating your chain, read on.

The rear derailleur is designed to move the chain up and down on the sprockets (or cogs) connected to your rear hub. Together these cogs are known as the rear cassette. By moving to a cog with fewer teeth, the derailleur gives the rider a faster (or higher) gear which is appropriate for flat areas or descents. By moving to a cog with more teeth, the derailleur offers a gear more appropriate for climbing hills (or a lower gear).

A threaded headset gets its name from the threaded steerer tube at the top of a fork. The steerer tube is attached to the inside head tube on a frame with an adjustable race. A threaded headset can be identified easily by the quill-type stem that fits inside the steerer tube. This article will discuss repairs and adjustments of a threaded headset.

Chainrings are the one, two or three large sprockets attached to the drive side of your crankset. Shifting from one chainring to another gives you different gearing options while riding.

A chainring is ready to be replaced when its teeth have become worn from use. Typical signs of the need for replacement are slippage of the chain and (rarely) excessive noise.

The easiest way to differentiate between a caliper brake and its counterpart, the cantilever brake, is to look where the brake is attached to the frame of your bicycle. If the brake is attached at two points, you have a cantilever brake. If the brake is attached by a single, centered bolt, you have a caliper brake. This article will discuss adjustments of the caliper brake.

A freewheel makes it possible to coast on a bike. When you are pedaling, the freewheel engages the sprockets, but it allows the rear wheel to turn when the pedals are at rest.

- A bicycle stand is always recommended
- A special tool designed specifically for your particular freewheel, known as a “freewheel puller”
- An adjustable wrench compatible with the hexagonal section of your freewheel puller
- You may need a bench-mounted vice for particularly stubborn freewheels
